Method and Apparatus for Data Capture Using a Voice Activated Workstation

ABSTRACT

A method and apparatus for capturing data in a workstation, wherein a large number of data associated with a sample which is viewed, by a user, through an optical device, such as a microscope, is to be entered in a computer related file. The optical device can be moved to a data-sampling position utilizing voice commands. A pointer can then be moved to an appropriate place in the file to receive the data relating to the data-sampling position. Data can be then entered in the appropriate position utilizing a voice command. The steps of moving the pointer and entering the data can then be repeated until all data is provided with respect to the data-sampling positions.

FIELD OF THE INVENTION

The present invention relates to a method and apparatus for data capture particularly speech recognition and text to speech technology for generating data reports or other formats in to a method and apparatus.

BACKGROUND OF THE INVENTION

Generating reports and collecting data in complex technology areas is always difficult. There may be a loss of data and this may easily be placed in the wrong column or row. Also if the person generating the report or collecting the data is conducting analysis or reviewing data inputs this can add further difficulties.

One technical area where there is particular issues is in the field of petrology. A geoscientist studying rock samples will have to carry out very detailed studies generating huge amounts of data. The accuracy of this data when being collected will be difficult.

In petrology the data collected includes data relating to the composition, origin, structure, and formation of rocks. The branch of petrology concerned with the description and classification of rocks is called petrography.

In the field of geological research, there are mainly four processes, which will be explained below.

Petrography is the examination of rocks in this section. Rock slices can be glued to a glass slide and the rock ground to 0.03 mm thickness in order to observe mineralogy and texture using for example a transmitted light petrographic microscope. Samples of sedimentary rock can be impregnated with blue epoxy to highlight porosity, which is the percentage of pore volume, void space, or the volume within rock that can contain fluids.

Micro paleontology is the study of micro fossils of which the majority are too small to be seen without the use of a microscope. Marine micro fossils such as foraminifera are important for stratigraphic correlation.

Palynology is the study of pollen and spores of plants. Changes in the Earth through time can be documented by observing changes in the fossils in successive strata and the environments in which pollen or spores were formed or preserved. Fossils can also be compared with their extant relatives to assess evolutionary changes. Correlations of strata can be aided by studying their fossil content.

A core is a cylindrical sample of rock retrieved from a bore. The average core length is often 60 feet and is generally stored in almost twenty 3-foot long trays. To analyse these core samples a geologist will start with a sheet of paper that contains the core depth in the first column. There are certain categories of columns that could be filled. Each category consists of subcategories that in some cases could add up to 100% more data.

In certain methods of operating, the geologist may use a camera and a petrographic microscope as part of a geological workstation for capturing and verifying geoscientific data in for example a spread sheet.

Typically, a geologist will examine a thin section of the rock sample under the microscope and will manually record the data on paper for later manual input into a table. This table could be a printed sheet of paper or a computer-based spread sheet. There is obviously much room for error in this process.

In petrographic data capture most of the time of the geologist time is spent in going back and forth between the microscope and the paper, identifying minerals and sizes of grains and recording this data. This is also true in micro paleontology and palynology, where geologists have to look at the microscope to identify micro fossils.

In the example of petrographic data collection each record should contain the description of one thin section sample which represents the microscopic evaluation of the sample for mineral and fossil content of the sample and other petrographic properties.

The current way in which this data entry is performed requires keyboard input and/or item selection via cursor control keys. There are currently two means or collecting petrographic data using only a microscope and using a microscope and camera.

In the case of the microscope only the geologist uses a transmitted-light petrographic microscope. The sample is divided into 4 zones. The zones are scanned as is shown in FIG. 1 to determine the contents. When a spread sheet of a rock sample description is to be produced, the data first have to be manually recorded in a draft report. The second phase is to create the final report by filling in either another final table or an electronic form displayed on a computer screen.

In the case of using a microscope and a camera connected to a PC, a geologist uses a transmitted-light petrographic microscope and a camera installed over the microscope to transmit the image to a computer screen. The counting is then done as above. When a spread sheet of a rock sample description is to be produced, the data can be directly filled into an electronic form displayed on a computer screen.

Speech recognition systems are sometimes used in the generation of structured reports and filling forms.

U.S. Pat. No. 5,051,924 (Method and Apparatus for the Generation of Reports), for example, discloses a general purpose apparatus for the generation of reports using a speech recognition system and a speech synthesiser to convert the text of the report to synthesized voice signals for storage and retrieval. More particularly, it relates to a system for storing and forwarding selected type of reports in the form of voice signals.

U.S. Pat. No. 5,465,378 (Report Generation System), also discloses a general report generation system which responds to selected user inputs for retrieving corresponding, previously defined report material and then compiles the retrieved material to form the report after the receipt of user inputs representing needed information.

OBJECT OF THE INVENTION

It is an object of the present invention to provide a system that is reliable in the sense that verification of the entered data will be done on-line during the creation of spread sheet or other document. It is another object of the present invention to allow for hands-free operation for data capture.

It is a further object of the invention to provide a workstation for geologists for at least capturing geoscientific data, the on-line verification of this data and the generation of on-line reports in spread sheet form during the examination of rock thin section samples using a petrographic microscope.

It is a further object of the invention to provide a workstation at least able to capture and verify all geoscientific data in a rock lab environment.

It is still another object of the present invention to provide a system which substantially standardizes the geoscientific data capture processes and saves time.

Still further objects will come apparent from the description hereafter.

DESCRIPTION OF THE INVENTION

The invention relates to the use of a camera mounted over transmitted-light Petrographic Microscope, an automatic speech recognition (ASR) system and a text-to-speech (TTS) system in a geological workstation for capturing and verifying of geoscientific data and for generating reports in for example spread sheet form during the examination of rock thin section samples.

FIG. 2 shows a schematic block diagram of the system of the present invention. The system includes a microphone 211 or other voice input means attached to an audio interface 212 which converts the speech signal into digital data that can be processed by a speech recognition system 213. The speech recognition system 213 is for example any conventional, commercially available speech recognition system such as the system marketed by International Business Machines (IBM) Corp. under the trademark ViaVoice.

Generally speech recognition systems are designed to recognise selected vocabularies and allow also for the addition of user-specific vocabulary. The speech recognisor, is generally a speaker-dependent system, that is, each user must train the system to recognise a vocabulary in his/her voice.

Once spoken words are recognised by voice recognition system 213, recognised text is sent to the Main Control Unit (MCU) 214. The MCU 214 is responsible for the generation and control of a spread sheet form as well as the control of a motorized microscope 218 through a stepper motor controller 217. The MCU 214 will be described in more detail later. The MCU 214 sends a confirmation text message to the text-to-speech system (TTS) 215. An example of the TTS system is a system such as the system marketed by International Business Machines (IBM) Corp. under the trademark “ViaVoice Outloud”.

The TTS systems receive a sequence of words, typically coded in ASCII, and generate a selected corresponding voice signal. The synthesized voice signals are output to a speaker (or earphones) 216 through the audio interface 212.

The MCU 214 sends a control command to the stepper motor controller 217 that is capable of moving the microscope at step sizes as small as 0.01 micron for X, Y and 0.002 micron for Z movement. A camera 219 mounted over the motorized microscope 218 is attached to a display interface 220 and converts the captured pictures into digital data that can be diplayed on a display 221.

A user may thus look at a sample through the microscope using pictures generated by the camera and microscope arrangement and record data relating to the sample in say a spread sheet using a combination of speech recognition and text to speech processes.

The Main Control Unit (MCU) 214, is shown in more detail in FIG. 3. This shows the main elements of the system that are responsible for the generation and control of the spread sheet as well as the control of the motorised microscope. The output recognised text from the speech recognition system 213 is the input to the MCU. The input text is first fed to the classifier 328 that will direct it to either the navigation manager 321 or to the vocabulary manager 323 based on whether the recognised text is a control command or a legal word (entry) that is part of the vocabulary belonging to the current active column of the spread sheet for example.

The navigation manager 321 is the component that is responsible for the interpretation of the spoken voice command and will decide the appropriate action based on a set of predefined rules 322. The action will be sent either to the form generation manager 326 or to the motor control manager 329 for execution. For instance, if the current cursor position is at column x and row y, the spoken command “move up N”, if recognised by the speech recognisor, will cause the cursor to move up to row y-N in the same column x. On the other hand, the spoken command “move focus right N”, if recognised, will cause the microscope stage to move right N steps (where the step size is to be set by the user in the user preferences 325). The navigation manager will also trigger the confirmation message generator 327 to generate a message to alert the user of the action that has been taken. The vocabulary manager 323 is the component that is responsible for the interpretation of the spoken data and will fill in the spread sheet with the appropriate entry based on a set of predefined relations 324 between the different members of the same category of data. In other words phrases or words which are common place or normal for the column in question.

Referring now to FIG. 4 flow chart of the method of the present invention is shown.

The process starts step 400. A sample is loaded into the microscope step 402. The first microscope position is established step 404. The movement of the microscope can be effected using voice commands; the speech recognition other voice commands ie by system 213 and then movement of microscope by the stepper motor in accordance therewith. It is clear that other means of moving the microscope can alternatively be used. Once the first microscope position is achieved the data input stage compenses 406.

This establishes:-

-   -   opening of the computer file into which data it to be loaded         (for example a spread sheet, database etc);     -   connection of the user to the speech recognition, text         recognition and MCU systems;     -   establishment of visual means by which the user can see the         sample; and/or     -   connection to an audio interface which enables the user to hear         commands and other information.

The user can now input a command step 408. The first command will position the cursor in the computer file in the appropriate location for data input step 410. The user then makes the necessary data input step 412.

The data input is made via voice commands and uses the resources of FIGS. 2 and 3 to accurately select the relevant text for entry into the computer file, as has previously been described. A determination is then made as to whether on not more data is to be entered into the computer file at the same microscope position. If yes (416) the process loops back to step 406 and the cycle of steps 408-414 are repeated until the answer to step 414 is no (418). When the answer is no a determination is made as to whether or not a new microscope position is required step 420. If no (422) the process ends (424). If yes (426) the system effects a step of moving the microscope 428. This establishes a next microscope position step 430. The system then loops back to step 406 and repeats steps 406-414 until the answer for 414 is no.

This system and method has been described with reference to geological data input. It may be useful in other technical fields where lots of data needs to be stored in a computer file whilst a user is looking at samples through an optical input, such as for example a microscope.
